The Heat Pack is a buildable item found on the Black Ops 4 Zombies map Tag Der Toten. It is used to survive in the freezing water for an extended period of time. It is built by finding parts scattered across the map and assembling them at a crafting table. One part is located at the Frozen Crevasse, another at the Lagoon, and a final one at the Lighthouse Cove.
- This is the final new buildable item in the Aether storyline, as it is in the final Aether Zombies map.
